摘要： A system providing flexible cyclic prefix length in a preamble (i.e., superframe preamble) is disclosed. The preamble comprises a first section and a second section. The first section contains at least one broadcast channel and occupies the first number of OFDM symbols in the preamble. The second section contains acquisition pilots and occupies the remaining number of OFDM symbols in the preamble. A first cyclic prefix length is used in the first section. It is indicated by the first broadcast channel and is unknown to a mobile station before the mobile station decodes the first broadcast channel. The second cyclic prefix length is used in the second section. It is fixed and known to the mobile stations. The first broadcast channel is located at the last OFDM symbol in the first section and is next to the second section in time.

摘要： In the system acquisition process system information is non-coherently detected using correlation of reconstructed and received preamble signals, such as the primary broadcast control channel (PBCCH) and the acquisition pilots (TDM1, TDM2, and TDM3). The phase correlation signals between the correlated signals of PBCCH and TDM2 or TDM3 and between the correlated signals of TDM2 and TDM3 are combined to decode other sector interference (OSI) information and the like. Acquisition is also made more efficient by taking advantage of predictable information based on system synchronicity. The sync/async bit is included in at least one of the acquisition pilots. The mobile then uses knowledge of system synchronicity to more efficiently detect the additional information in the superframe preamble.

摘要： A system of methods and constructs that enable multiple users to simultaneously share transmission (i.e., radio) resources, while reducing delay for users with delay-sensitive applications, is disclosed. The system provides for: forming one or more than one shared persistent (or “sticky”) assignment (SSA) group in a sector; allocating more than one shared sticky resource in at least one SSA group; and dividing users into at least a first class of users and a second class of users. The first class of users is given a higher priority to access the shared resources than the second class of users when the shared resources become available for a new packet. The first class of users is also given more choices of shared resources when starting transmission of a new packet.

摘要： Techniques are provided to assign radio resources with one of two or more types of assignments on a frame-by-frame basis. The first type of assignment uses subcarriers that are contiguous in both time and frequency, and the second type of assignment uses subcarriers that are disjoint and equally-spaced in frequency. The types of resource assignments can be multiplexed in a frame by dividing the frame into two zones, each zone of a different type. The demarcation between the first and second zones is implicitly indicated by the assignment messages for the mobile stations. Based on the loading conditions, the base station selects one of two demarcation strategies to use and communicates the selection implicitly by using one assignment message for a mobile station.
